An ‘Alien’ Thought Experiment — “Could Advanced Life in Near-By Star Systems Have Observed Earth Over the Eons?”

“Perhaps,” Harvard astrophysicist Avi Loeb told The Daily Galaxy: “We developed our modern science and technology (including transit astronomy and radio communication capabilities) only over a century out of the 4.5 billion years of the Earth’s lifetime. The window of opportunity for anyone to notice us at a random time in Earth’s history is roughly  one part in 45 million (4.5 billion divided by 100 years). 


“UFOs Were Farside Speculation, Now They’re a National Security Concern”

The Washington Post reported today that official Washington “is swirling with chatter — among top senators, Pentagon insiders, and even former CIA directors — about UFOs. What was once a ticket to the political loony bin has leaped off Hollywood screens and out of science-fiction novels and into the national conversation.”


“Alien Evolution” –Advanced Extraterrestrial Life Will Mirror Homo Sapiens

But they may be billions of years older. Scientists are making predictions about the biological make-up of advanced, complex aliens, offering a degree of insight as to what they might look like.


“The Radio Species” –Scientists Doubt ‘Human Niche’ Would Be Filled If We Go Extinct




For what purpose did the human brain evolve is a question that has puzzled scientists for decades.In 2010 Colin Blakemore, an Oxford neurobiologist argued that a mutation in the brain of a single human being 200,000 years ago turned intellectually able primates into a super-intelligent species that would conquer the world. Homo sapiens appears to be a genetic accident.


Stephen Hawking’s Great Question –“Why Isn’t the Milky Way Crawling With Mechanical or Biological Life?”



“If the argument about the time scale for the appearance of life on Earth is correct”, Stephen Hawking observed, echoing Enrico Fermi’s infamous question–Where is Everybody– “there ought to be many other stars, whose planets have life on them. Some of these stellar systems could have formed 5 billion years before the Earth. So why is the galaxy not crawling with self-designing mechanical or biological life forms?”


Alien Rain –“A Key to Revealing the Ancient Climate on Planets like Mars and Potentially Habitable Exoplanets”




“The insights we gain from thinking about raindrops and clouds in diverse environments are key to understanding exoplanet habitability,” said Robin Wordsworth, Associate Professor of Environmental Science and Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) about a new study of the behavior of raindrops on other planets that is key to not only revealing the ancient climate on planets like Mars but identifying potentially habitable planets outside our solar system. “In the long term, they can also help us gain a deeper understanding of the climate of Earth itself.”
